Definitions
- the invention relates to a ceramic multilayer component with a varistor and its manufacture
- Discrete components with varistor function can be used as protective components against ESD (electrostatic discharge).
- ESD electrostatic discharge
- One possible use is z.
- high-frequency filters for example, for mobile, in the frequency range of 0.5 - 5 GHz to protect these filters or to protect downstream or upstream electronics such as SignalVerproofrn.
- these devices can also provide EMI protection. It is therefore a so-called EMI-ESD protection device.
- the object of the present invention is therefore to specify a monolithic ceramic multilayer component in which, in addition to a varistor function, at least one other component function is integrated, without the varistor functionality being unduly impaired as a result.
- a dielectric ceramic material was found which can be co-sintered with a varistor ceramic to form a monolithic multilayer component according to the invention.
- the multilayer component therefore comprises at least a layer of a varistor ceramic and another layer of a dielectric. Both layers can be arranged directly adjacent in the multilayer component. At sintering, interdiffusion between the layers limited to a narrow reaction zone of typically 1 ⁇ m between the two layers occurs at best, which at best negligibly negatively affects the electrical properties of the varistor.
- the critical varistor properties such as low reverse current and high pulse stability are retained in the multilayer component.
- metallizations are arranged on or between the ceramic layers, which are structured into conductor sections and metallized surfaces.
- the metallizations form together with the ceramic in addition to a varistor at least one further component which is selected from at least one of the component functions capacitance, resistance and inductance.
- the inner metallizations are introduced prior to sintering, metallizations arranged on outer layers or side surfaces can also be produced or applied after the sintering of the multilayer component.
- Conductor portions and metallized areas disposed in different levels of the multi-layer device may be electrically interconnected by vias through one or more layers.
- all integrated individual components can be electrically interconnected and together result in a functional circuit, for. B. an RF filter circuit.
- the dielectric consists of different proportions of the following three stoichiometric compounds: Zn 3 TaO 8 , Zn 2 TaO 6 and Bi 2 Zn 2 / 3Ta 4 / 3 ⁇ 7 .
- the mixture contains at least one of the compounds mentioned.
- individual ions may be partially replaced stoichiometrically in the compounds.
- the Zn may be partially replaced by one or more of Ni, Co, Fe, Cu, Mg and Ca.
- Zn is advantageously up to a maximum of about 30 atom% replaced by one or more of said ions.
- Zn can also be replaced by Ca and Mg up to 100%.
- Ta may be partially replaced by Nb.
- compounds are preferred in which only a smaller part of the Ta is replaced. With too much Nb there is a risk in individual cases that the sintering temperature is too low and the diffusion becomes too great.
- the Bi may be partially replaced by one or more rare earths, selected in particular from La and Nd. Bi is advantageously up to a maximum of about 30 atom% replaced by one or more of said ions.
- M stands for Ni, Co or Ca.
- SE stands for one or more rare earths.
- index x, y and z which in each case gives the proportion of the ions replaced in each case relative to the starting compound, independently of one another 0 ⁇ x, y, z ⁇ 1 applies. This means that not all portions of the parent ions are replaced or absolutely none.
- X and z are advantageous as already mentioned above to max. 0.3 and y to max. 0.5 limited.
- the varistor ceramic may be based on a doped zinc oxide. This can be doped with Bi and Sb as Hauptdotierstoff to each about 3-5 atom%. At least one of Ni, Co and Cr may also be present in a proportion of up to about 0.5 atom% as secondary dopants.
- varistor ceramics based on doped zinc and praseodymium oxide are compatible with are the dielectric and can also be sintered without substantial restriction of the varistor functionality together with the proposed dielectric.
- a dielectric constant of about 400 results.
- the dielectric constant of the dielectric is generally between 20 and 100, and thus by a factor of 5 to 10 lower. This results in a broad selection range for the component functions that can be realized with them, with which virtually all useful values for the component functions can be set.
- the variability in the design of circuits is substantially increased and therefore improved.
- the structured metallizations that form the integrated L and C elements can be arranged on one and both sides adjacent to a layer of the dielectric and use this as a dielectric.
- components which use the varistor ceramic as a dielectric can also be formed in the multilayer component.
- the multi-layer component requires a sintering temperature of 950-1300 0 C.
- the metallizations can be made of a conductive paste whose metallic components z. Ag / Pd alloy or Au. Pure silver is not suitable because of the high sintering temperature.
- the layers with the varistor ceramic and the dielectric can be arranged directly adjacent to one another or in the stack of the multilayer component one above the other.
- a multilayer component may have a sandwich structure, in which a respective other of the dielectric or the varistor ceramic is arranged between two identical layers of the varistor ceramic or of the dielectric, wherein the layers are arranged directly above one another in sandwich construction.
- one or more further foreign layers of other materials may be included as partial layers, if it is excluded that they are in direct contact with the varistor ceramic.
- various passive components can be integrated, wherein in addition to a varistor nor R and C, L and C, or R, L and C elements are integrated.
- an RF filter circuit made of R, C or L elements can be integrated in the monolithic block, wherein the varistor can be connected as a protective component parallel to the RF filter circuit to ground.
- the varistor fulfills two functions as ESD and as EMI protection. Through its varistor function, it can harmlessly derive harmful current pulses, which are typical for ESD.
- a varistor usually has a capacity due to its design. With a capacity in a parallel branch to ground he therefore fulfills a rudimentary filter function with a stopband. By suitable dimensioning or by a suitably selected capacitance value of the varistor, this blocking region can be suitably selected or set become.
- the varistor can also function as an EMI protection device.
- first green sheets for the layer (s) of varistor ceramic and second green sheets for the dielectric are produced with the aid of a binder, preferably an organic material of corresponding viscosity, for example by film casting.
- the metallizations are printed on the green sheets on one side and on both sides with a sinterable conductive paste, for example by means of
- At least one first and second green sheets are placed one above the other, aligned with respect to the metallizations and laminated together to form a film composite. Then the film composite is sintered together.
- Vias are punched into the green sheets at corresponding points provided for through-contacts and filled with a conductive material before the sheets are laminated to the film composite.

- two electrodes Ell and E21 or E12 and E22 in the form of a baked-in conductive paste are formed on one layer surface at a distance from one another. Belonging to the same electrode metallizations Ell and E21 or E12 and E22 are interconnected by a feedthrough DK.
- the varistor functionality can now act on two electrode pairs.
- each layer can comprise a plurality of similar sublayers, between each of which structured metallizations are arranged.
